大多数中和SARS-CoV-2的人单克隆抗体(mAb)识别刺突(S)蛋白受体结合结构域,并阻断病毒与细胞受体血管紧张素转换酶2的相互作用。我们描述了一组人单克隆抗体结合的N-末端结构域(NTD)的S蛋白从SARS-CoV-2恢复期捐助者的不同表位,并发现这些少数具有中和活性。COV 2 -2676和COV 2 -2489单克隆抗体对SARS-CoV-2和VSV/SARS-CoV-2重组病毒的感染均有抑制作用。我们通过丙氨酸扫描诱变和选择功能性SARS-CoV-2S中和逃逸变体来定位它们的结合表位。机制研究表明,这些抗体通过抑制感染周期中的后附着步骤部分中和。C 0 V2 -2676和C 0 V2 -2489作为预防或治疗提供保护,并且Fc效应子功能是最佳保护所需的。因此,自然感染诱导了一组有效的NTD特异性mAb,这些mAb利用中和和Fc介导的活性,利用多种功能属性来保护免受SARS-CoV-2感染。Suryadevara等人发现针对SARS-CoV-2自然感染产生的刺突蛋白N端结构域的人类中和抗体。这些抗体抑制病毒周期的后附着步骤,并通过抗体Fc结构域启动保护性免疫应答。
Most human monoclonal antibodies (mAbs) neutralizing SARS-CoV-2 recognize the spike (S) protein receptor-binding domain and block virus interactions with the cellular receptor angiotensin-converting enzyme 2. We describe a panel of human mAbs binding to diverse epitopes on the N-terminal domain (NTD) of S protein from SARS-CoV-2 convalescent donors and found a minority of these possessed neutralizing activity. Two mAbs (COV2-2676 and COV2-2489) inhibited infection of authentic SARS-CoV-2 and recombinant VSV/SARS-CoV-2 viruses. We mapped their binding epitopes by alanine-scanning mutagenesis and selection of functional SARS-CoV-2 S neutralization escape variants. Mechanistic studies showed that these antibodies neutralize in part by inhibiting a post-attachment step in the infection cycle. COV2-2676 and COV2-2489 offered protection either as prophylaxis or therapy, and Fc effector functions were required for optimal protection. Thus, natural infection induces a subset of potent NTD-specific mAbs that leverage neutralizing and Fc-mediated activities to protect against SARS-CoV-2 infection using multiple functional attributes. Suryadevara et al. find human neutralizing antibodies to the spike protein N-terminal domain that arise from natural infection with SARS-CoV-2. These antibodies inhibit post-attachment steps of the viral cycle and initiate protective immune responses via the antibody Fc domain.
